Question 273125: The number of golf balls ordered by customers of a pro shop has the following probability distribution:
x 3 / 6 / 9 / 12 / 15 /
______________________________________
P(X) 0.27 / 0.17 /0.33 / 0.12 / 0.11 /
I know the mean is 7.89 and the standard deviation is 3.88
u=sum(x times P(x)) divided by P(P(x))
I'm not sure what is the process of this question
Find the probability of six or more golf balls being ordered?

Find the probability of six or more golf balls being ordered?
--------------------
Adding the P(x) values you see they sum to 1.
----
So, P(x >= 6)
= 1 - P(x=3)
= 1 - 0.27
= 0.73
